Overview of Development Support System

A speech synthesis LSI development support tool of LAPIS Semiconductor is a software tool and hardware tool supporting the development by the customer.
This support tool is comprised of the SDCK(Sound Device Control Kit) and the reference board mounting the LAPIS Semiconductor's speech synthesis LSI, and can perform various operation from editing sound data to creating ROM data from sound data, writing ROM data into the device and listening to the sound playback for evaluation. The third party's on-board programmers are also availavle for some of the products.

Sound Device Control Kit

The SDCK(Sound Device Control Kit) consists of both hardware (SDCB2) and software (Speech LSI Utility).
This development tool is used for editing sound data and also creating ROM data from sound data /writing ROM data into the device/listening evaluation for the LAPIS Semiconductor's speech synthesis LSIs. *A reference board is necessary for a writing and listening evaluation of ROM data .

Operations form waveform editing to speech playback are easily performed.

All products of LAPIS Semiconductor's speech synthesis LSI are suported.

Compact size (70mm×90mm*) * SDCB2 board

To utilize the Tool, your PC is required to meet the following system requirements :

The SDCB2 (Sound Device Control Board 2) can be used for all of LAPIS Semiconductor's speech synthesis LSIs. The SDCB2 supports OTP/Flash writing and listening evaluation by connecting a reference board.

* The SDCB2 can not be used for writing in mass production. the sound's ROM data needs to be written into the device at the factory of LAPIS SEMICONDUCTOR, or written by using the on-board writer.

The reference board is used by connecting with the SDCB2 and enables writing OTP/Flash ROM data into the target device and listening evaluation using the actual speech synthesis LSI. The reference board is also used by conncting with the microcontroller on the customer's system board for evaluation.

*1 : When it connects with SDCB2, The optional (mode) function is not usable partly.

*2 : The reference board is equipped with flash ROM 16Mbit.

*3 : This speech synthesis LSI cannot be written.

*4 : The ML2282X/ML2286X/ML2272X/ML2276X is a design sample for checking the functional operations of the speech
synthesis LSI device, we cannot guarantee the reliability and quality including the writing quality of sound data.

Flash ROM type supports on-board writing tools.
